• Introduction• Body-centric Interaction • Recurring Design Themes • Body-centric Browser • Design Issues & Challenges• Conclusion & Future Work
2
Introduction (1/6)
• Modern mobile devices rely on the screen as a primary input modality
• Interaction tedium is exacerbated as mobile applications increase in both number and complexity
3
Introduction (2/6)
• Prior work has suggested various solutions to address this ‘small-screen’ problem
4
people place digital information
onto different body parts
Introduction (3/6)
• Prior work has suggested various solutions to address this ‘small-screen’ problem
5
create virtual workspaces around a person’s body
Introduction (4/6)
• Prior work has suggested various solutions to address this ‘small-screen’ problem
6
orients the device to ‘peep into’ and navigate an information space
envision a wearable mobile device
Introduction (5/6)
• It is difficult to distill ‘guidelines’ that stimulate new mobile interaction designs based on a person’s body and the space anchored to it
7
Introduction (6/6)
• Goal– Develop Body-Centric Interaction with Mobile
Devices – Explore the breadth of this design theme, where
go beyond point solutions in an attempt to create a network of design ideas
8
Body-centric Interaction (1/4)
• Implementation Technologies– Identify the body location that the mobile device
is referring to (RFID tags | either fiduciary tags or shapes imprinted)
– capture the fine-grained changing spatial relationships of the device relative to the body (infrared cameras & proximity Toolkit)
9
Body-centric Interaction (2/4)
• Storing and retrieving digital objects (bookmarks, photos, etc.)
10
Body-centric Interaction (3/4)
• Triggering digital shortcuts (making a phone call, starting the music player, etc.)
11
Body-centric Interaction (4/4)
• Controlling applications (navigating the calendar time line, selecting from a set of tools, etc.)
12
Recurring Design Themes (1/3)
• Situating Interactions in the Body’s Proximal Spaces– Pericutaneous space <-> On-body space– Peripersonal space <-> Around-body space
13
Recurring Design Themes (2/3)
• Tracking the Device-to-Body Spatial Relationships
14
Recurring Design Themes (2/3)
• Tracking the Device-to-Body Spatial Relationships
15
Recurring Design Themes (2/3)
• Tracking the Device-to-Body Spatial Relationships
16
Recurring Design Themes (3/3)
• Considerations for Mapping the Interactions– Physical constraints– People's kinesthetic sense– Visual cues– Associative experience
17
Body-centric Browser (1/2)
• Scenario
18
Body-centric Browser (2/2)
• Design– Displaying and managing opened tabs:
the tab navigating zone– Bookmarking tabbed web pages:
the bookmark zone– roviding control options with tabs:
control zone
19
Design Issues & Challenges
• Scalability• Search and Find• Social & Cultural Concerns
20
Conclusion & Future Work
• Body-Centric Interaction with Mobile Devices contributes a class of mobile input techniques
• A bottom-up path of prototypes explored how such interactions can be realized
• We need robust and reliable enabling technologies that people can use and enjoy in their daily lives
